recently announced that it will miss its 2026 ROE target and attributed the miss to

lower interest rates in some African countries in which it operates, notably Ghana.

South African banks provide limited disclosure regarding their African operations, so

we used all available disclosures to quantify each bank’s exposure to each African

country. We then estimated net free funds per bank per country and used that,

together with changes in interest rates in each country, to forecast the net impact of

reduced endowment on each bank’s NII in 2026. We performed reasonability tests of

our estimates against banks’ disclosed NII sensitivities.
